- "The Sauropod looked like a Datousaurus, a fifty-foot long Middle Jurassic herbivore whose fossils were found in the the Dashanpu Quarry of central China. But...
How could a dinosaur that large make it into this clearing- unless there was another way in that he [Alan Grant] hadn't spotted?"

Datousaurus was a sauropod from the Middle Jurassic Period. Part of the same family as Mamenchisaurus and related to Shunosaurus, its name means "Big-headed Lizard" in Chinese. Datousaurus lived in the lower Shaximiao Formation in Dashanpu, Zigong Sichuan province in China. Datousaurus was discovered by Doug Zhiming and Tang in 1984 where only two partial specimens were discovered. Both Datousaurus and Shunosaurus were similar in anatomical ways. Datousaurus' teeth were well developed for grazing in different sized trees, as well as raised vertebrae; highly developed for the latter reason.
Jurassic Park III (novelization)
- The mention of Datousaurus in the film novelisation is because in the script the carcass was intended be a sauropod before being replaced by Parasaurolophus. This is due to the prop for the latter pre-existing thanks to being made for an alternate opening for The Lost World: Jurassic Park.
